问题描述

对于这个问题中稍微长的有风代码，提前采用这种方式

Apoologies in advance for the slightly long winded code in this question

}


#leftcol {
    background-color:#800080;
    width:125px;

#leftcol img {

    margin-bottom:20px;
}

.content {
    padding:20px 10px 10px 20px;

<!-- admin classes -->
.pageselect p {
    color:#C90;
}


#rightcol {
    /*background-color:#800080;*/   
    width:160px;
    min-height:330px;
    float:right;
}

.righthead {
    margin-top:7px;
    background-image:url(../images/rightcol-head.png);
    color:#FFF;
    padding: 5px 20px 5px 20px;
    font-size:14px;
}

.rightmid {
    background-image:url(../images/right-mid.jpg);
    padding: 5px 10px 5px 10px;
    font-size:14px;
}

.rightfoot {
    background-image:url(../images/right-foot.jpg);
    background-repeat:no-repeat;
}

.clear {
    clear:both;
}

#footer {
    background-color:#800080;
    width:880px;
    min-height:30px;
    margin-top:-20px;
    padding-top:30px;
    padding-left:20px;
    padding-bottom:10px;
}

#footer p {
    color:#ffff00;
}

#footer p a {
    color:#ffff00;
    text-decoration:none;
}

#footer p a:hover {
    font-weight:bold;
}

.error {
    color:#C30;
}

我有上面的样式表。我试图风格下面的元素（取自firefox web开发工具）：

I have the above stylesheet. I am attempting to style the following element (taken from firefox web developer tools):

html > body > div#wrapper > div#leftright > div.content > div.pageselect

在我看来，.pardselect应该是选择器，但我似乎无力影响风格，它只是给我wacko！

To my mind .pageselect should be the selector to do that, but I seem to be powerless to influence the style, and its just about sending me wacko!

为什么不工作？

编辑注释：

<div class="pageselect">
<p>
page
</p>
</div>

一切都由一个id自己定义或者由一个类来定义，就像我的代码。

Everything is defined by a id on its own or by a single class, just the way I code.

在您的CSS中发表评论？

<!-- admin classes -->
.pageselect p {
    color:#C90;
}

这应该：

/* admin classes */
.pageselect p {
    color:#C90;
}

请注意，在某些浏览器中，CSS规则的选择器可以分布在两行：

Take note that in some browsers a CSS rule's selector can be spread between two lines:

.pageselect
p {
    color:#C90;
}
/* that was the same as
.pageselect p {
    color:#C90;
}
*/

所以你的HTML注释 <！ - - > 被解释为CSS选择器的一部分。因为它作为一个CSS选择器没有意义，你的整个规则被删除。

So your HTML comment <!-- --> is being interpreted as part of a CSS selector. Since it makes no sense as a CSS selector, your whole rule is dropped.
